It's worth noting that I only did Remix for like 6 months last year. My big issue was it's intentional inflexibility. It creates a very narrow and inflexible mold for you to build your site into, creating a framework where the "cure" is worse than the problem. They make a huge selling point of loading nested data, loading the nested components with their data in parallel. I have never seen that to be a huge problem, in my experience of React - complexity has been the problem, and that's something that Remix makes worse, not better.

I too quite like Remix and I think the framework is taking off! The support of Shopify has made Remix quite popular, especially with the Hydrogen offering. I cannot comment on the community though, I've only had decent experiences during the earlier Remix days.
